That would happen to a Giga if you placed it in a Rex environment. New predators and a very differrent climate.

new predators an major clmimate change

I agree with opinion of this post. Nice job Mr. Happy.

Millions of years probably. Allosaurus was sitting at the top for 10-20 million years, then, in the blink of an eye, it vanished. A super predator that was so well adapted to taking on just about anything, couldn't adapt.

it would not take long

The question is, how long would it take them. If it takes too long, then they're dead.

the super predators would adapt

Thanks Rex Fan.

The temperature difference could be a factor though. Minor, but it could play a role. 

By the logic that Giga could survive well in N. America like Predator X is saying, then T.rex should do just fine in S. America. I do agree there is evidence for iguanodonts in S. America, but sauropods ruled. There were smaller species like Saltosaurus and I think T.rex could hunt them, but it wasn't in it's comfort zone, that's for sure. Let's see about Giga though. A pack of 5-6(which is based on the evidence we have) would probably have trouble against an adult Alamosaurus at some 90-115 ft long and 80-110 tons. Hadrosaurs were fast and smart(for herbivores), and ceratopsians/ankylosaurs were armed and armored.

Good post anyways :)

Hadrosaurids were defiantly common and giga knew how to hunt them

Yeah, I meant more so remove Rex and put Giga in its place, remove Spino and put Rex in its place, etc. 

Thanks SFKing.

An interesting list. I do agree with the opinions in this discussion.

But why, rex and giga would not compete much. And the predator-prey ratio is 3 to1 so giga would do fairly well

Also, sauropods weren't common in late cretaceous North America. 

The old, young and sick are always the obvious ones. It's possible for Giga to last in North America 65 million years ago, but the whole point is it probably wouldn't last long. 

Alamosaurs is not amphiceolias sized ya know. a pack of gigas could take one. And if you disagree with me . Then I can say that they can take the weak old young sick and injured. And there were hadrosauridsin patagonia 70 million yeyears ago where giga also lived.

as for your expirement it didn't work it was easy to do

Edmontosaurus was small compared to what Giga was used to, and Alamosaurus was simply too big for even a large pack of Giga. Also, it would be difficult for Giga to get a good bite in on Edmontosaurus. 

To show the importance of depth perception, try this little experiment. Close one eye, reach as far as you can with both arms, and try to touch your pointer fingers together. It's harder than it sounds. 

Edmon was not small and there wete a few sauropods that lived with rex that giga could hunt such as alamosaurs 

Like I stated, the lack of depth perception would make hitting small targets rather difficult for Giga. 

Um why would giga have trouble killing hadrosaurids

As i know the biggest giganoto is the most fragmentary so tell it's size as a fact is...you know...i'm not going to say any bad words.maybe giga was only 13,5m or maybe it was 15 m.but the real question is that how big was the giga's follower on the S-american throne?

I'm pretty sure this is the very first time that Polacanthus was used on this site for anythingm fight or General topic. 

Thats a hard one... I will give you my top five dinos:

5. Utharaptor

4. T-Rex

3. Carnotaurus

2. Velociraptor

And number one is.....

1. Spinosaurus!!

Nice and impress Carno. Glad you didn't overput Tyrannosaurus Rex at 15m long and a weight of 10-12 tons like fans due -_-

12.7-13.2m is a max estimate in my book and a weight of 8-9 tons.

Again, great post!

I would love to see Carno as the new villain in the 4th movie :)

Theres been plenty of fights and discussions featuring carnotaurus, but polacanthus? i don't believe so

I do not believe so, I believe it's the bust for JW.

They may share the same basic build/Sculpt, But I Haven't fully seen both of the Busts from SDCC. 

*Nor have I compared them yet.

I try not to, but that there is the majority of the human population for ya, most are not in the best of moods when they are sick.

Also, I'd like to point out that when it comes to strength, it varies greatly depending on what part of the body you're examining. So, now for my lists.

List 1: Bite Strength.

1. T. rex. (no real surprise there)

2. Carcharodontosaurus.

3. Spinosaurus.

4. Giganotosaurus. (Placed in last due to it most likely bleeding its prey to death)

List 2: Arm Strength

1. Spinosaurus. (This predator likely relied on its arms more than the others)

2. Giganotosaurus (Would've helped with bleeding out its prey)

3. Carcharodontosaurus

4. T. rex (don't even pull the fact that it could lift 450 lbs, that's irrellevant compared to the others arms.)

List 3: Bone/Skeletal Strength

1. T. rex. (The sturdiest carnivorous dinosaur ever. No question.)

2. Giganotosaurus. (Essentially a beefier Carcharodontosaurus)

3. Carcharodontosaurus.

4. Spinosaurus. (That sail is a liability, and if its legs are as scrappy as sereno's model shows them to be...)

Well, don't let that cloud your judgement.

Well ive seen you guys do the same, and on top of that im sick today and not in the best of moods.

We're just making some points, something you do quite a bit. Don't get so defensive.

I will say, fish are very high in nutritional value

Are you trying to disprove me or what, because it isnt going to work due to me doing large amounts of research of the regualar bases, especially now that im in paleobiology and paleontology. Yes, of course, T-Rex had other T-Rex's to worry about, as well as the other dinos listed, but they other have more than just themselves to worry about, as i have already stated. And its not about nutrition here, its about Spinosaurus probably not having the patience just to sit there and wait for a fish that definately isn't sure to be his, so it did what any other predator would do and go for the easier kill with less patience at risk.

S-rex, spinos weight is now 6 tons...

As a fight or as a whole, because my second discussion ever was about Carnotaurus.

s- rex, trex had other trex's or worry about, we have various fossils showing rex biting each other and such. And spino at the top? It was the lightes compared to size, at somewhere between 6 tons to 9 tons. And those fish did provide large amounts of nutrition, and the fish were plentyfull.

1. T.rex(by a longshot)

2. Giga

3. Carchar

4. Spino(though it and Carchar are close)

Here's my opinion:

1. Spinosaurus

2. Charcarodontosarus

3. Giganotosaurus

4. T-Rex

Now, heres my reasoning to why i put these in their place:

1. Spinosaurus, i think, was definately the strongest due to its immense size, competition, and like i've always stated, a 12-15 ton monster does not simply feed on mainly fish, as it would need the energy to wait and finally attack its slippery meal it doesnt always get to call its own (much like a fish getting off of our hooks today). Something that big needs to have energy constantly restored into its body, so it needs something BIG to constantly replenish its appetite each time it needs the energy to have it for its next ambush, for defending itself against other large predators, or simply just walking around to find other neccesities.

2. Charcarodontosaurus i put at two simply because of its weight mainly (7-9 tons). This is because a body that is 40-46 ft long divided into 7-9 tons doesnt seem like it would be too heavily muscled. Yes, it was definately powerful, it preyed on sauropods a whole lot and needed the strength to do so, but it didn't have as much muscle in itself as my number one pick due to one sauropod being enough to feed it for a week, where as Spinosaurus used its energy up so quickly it needed to feed almost all of the time, which the exercise to find its prey and take it down kept it strong and muscular.

3. Giganotosaurus is my #3 because of the less competition of the last two. Yes, there was some, but none of its competetors were close to its size, which it used to scare away the smaller predators from their kill. This leads me to ultimately get to my point of it not having to really hunt or defend itself from other predators as much as the previous two, as it could just scare away other competition, but not as much as my #4 pick's strength...

4. Tyrannosaurus, yes, i know a lot of you would like to argue with me about this, but Tyrannosaurus had little to no competition whatsoever. A lot of the time, it would find a fresh kill made by much smaller predators with its keen sense of smell and steal it from them, due to it being much larger than the ones who actually killed it. Its much like MRE's for T-Rex, as it can find and scavenge already dead animals with little effort as to getting it, as no other predators would even think twice about defending their own kill against T-Rex, even if it starved them. Now im not saying T-Rex was a pure scavenger, but it only really went out and killed its own food when it couldnt find carcasses laying around. With this being said, it probably had a higher weight than the last two, but that is due to fat, not muscle, because it didnt get the exercise all of the above did because it didnt have to look far for its next meal, nor fight for it, which it is pure logic that if you dont have to walk nor do it because you dont have the common sense to do it due to getting exercise (which no dinosaur had because it has to do with your environment and competition, which keeps you moving depending on the environment, competition, size, and overall, fight to survive!)

The reason I belive, giga was stronger carchar is....

Carchar, actualy has a more slender, bulid then giga, and was most likely lighter...
